Circular on tds 194j

Does any one have circular that issued regarding services which include GST will be excluded while deducting the TDS amount.  If the bill value is 30,000+ 5,400 (18%) = 35,400 and if we make single payment normal it needs to be deducted 10% as per new amendment we can exclude that 5,400 and need not to be deduct the TDS.  If any one having circular on above please send me.
